SPEGIFICATION forming part of Letters Patent No. 469,161, dated February16, 1892.

Application filed October 29, 1891. Serial No. 410317. (No model.)

To all whom it may concern.-

Be it known that I, RUFUS S. MERRILL, of Boston, in the State ofMassachusetts, have invented a new and useful Heating Attachment forArgand and Other Lamp or Gas Burners, of which the following is aspecification.

It is my object to provide a device for utilizing for heating purposesthe heat emitted IO by burners of the kind known as Rochester burnersand other burners of the Argand type, this device to be one that can beapplied to the burner at will without requiring any alteration in thelatter and without interfering with its usefulness as a light-givin gagent. The device which I have devised for this purpose is a broadshallow sheet-metal heatingchamber, the bottom of which is imperforate,save at the center, where it has a socket to receive the chimney,provided with holding tines or projections to catch over or rest uponthe top of the chimney, and the top of which is pierced at or near itsrim with small holes, in number and size sufficient to permit thepassage of the heated air with such freedom as not to interfere with thedraft of the burner. The heated air from the chimney strikes against theimperforate central portion of the top and is thence deflected outwardlytoward c the rim of the heater,where it escapes through, in dividedcondition, the many small holes therein, heating the surrounding air andacting under these conditions as a very efficient agent, sufficient toheat small rooms-such, 5 for example, as sewing-rooms or bath-roomsin avery thorough manner.

The device is light and is not at all unpleasing to the eye, it can bereadily fitted to and removed from the chimney of any burner,

0 and requires no alteration in existing burners or chimneys.

The acccoinpanyin g drawings represent my device in the best form atpresent known to me. Figure 1 is a vertical central section of the 5same as it. appears on a lamp-chimney, the upper part of which latter isrepresented in the figure. Fig. 2 is a plan view of the device. Thedevice is composed of the two shallow dished disks A B, of sheet metal,united at their peripheries by a vertical band a, which in thisinstanceis formed in one with the upper sheet-metal disk A. In this waya shallowed sheet-metal drum is formed. The lower disk B is imperforate,save at the center, where an opening is formed in it for the chimney,this opening being surrounded by an external sheet-metal collar 6, ofsufficient size to receive loosely the top of any ordinary lampchimney0. Within and fixed to the collar are spring inwardly-bent wires 0,capable of being sprung apart to receive the chimney between them and toclasp itsufficiently closely to hold the heating appliance steady on thechimney. They are provided at their inner upper ends with hooks .c orthe like to catch over or rest upon the top of the chimney. 'There maybe three or more of these holding devices 0. The top disk A isimperforate, except near its rim, where it is provided with numeroussmall slits or holes a: 1 for passage of the heated air.

In order to protect the central portion of' disk A from being injuriously affected by the excessive heat discharged from thelampchimn'ey,I prefer to interpose between it and the chimney a thindeflecting-shield D, se-' cured to the top A by legs or supports d.

hen it is desired to use this device with a lighted lamp, all that isrequired is to put it on the chimney in the position shown. The heatedair discharged from the chimney strikes against the imperforate top ofdisk A or against the shield D and is deflected outwardly to the holes00 y, through which it passes in finely-divided condition, thus heatingthe surrounding atmosphere. The drum itself has its sheet-metal parts AB highly heated also, and this acts further as a heating agent.

Having described my invention, what I 0 claim, and desire to secure byLetters Patent, is-

As a new article of manufacture, the herein-described heating attachmentfor Argand and other lamp or gas burners, consisting of the two disheddisks A B, united at their edges to form a shallow drum having an imper-In testimony where-ofI affix my signature in forate bottom, except for acentral chimneypresence of two witnesses. receiving opening, and a topimperforate in 7 y the center and perforated near its rim, the (301-hUFUS MERRILL 5 lar b, surrounding the chimney-opening, and WVitnesses:

the spring hooks or clasps c, as hereinbefore EWELL A DICK, shown anddescribed. 1 L. O. HILLS.
